At the back of the classroom is a mango tree made of wood, which teacher Esnart crafted with the help of two Belgian students. The branches of the tree are filled with objects that the children bring from home. Every morning teacher Esnart uses her mango tree so the toddlers learn to express themselves, and she links the objects to one of the learning domains. "In this way I have a lot of starting material for my lesson," says teacher Esnart.
